THOMAS E( PETERS, or MOBERLY, Missouan i 'G,|=x'rsASI-:'c uP.

' f Be it known thatfl, .THOMAS E. PETERS, a

citizen of the United States, residing at Moberly, in the county of Randolphand State of Missouri, have invented. certain new and usefulV Improvements in Grease-Cups, of

" whichfthe followin isa specification.

This invention re ates to oil-cups, andper-y x ltainsto the"class of such oups known as grease-cups having telesco ing feed-plugs ,-.sldabletin the cup-shell and 'orming a stopper or closure lfor the cup.

n The object, primarily, ofthe invention is to provide ak grease-cup with a plunger which shall control the .flowof grease from the cup and which shall forma closure for thecup 'ger carried by the cup-stem.

land containa `portion ofthe lubricant.v

' Afurther object of the invention is to ro'- vidc a feed4 plungeror plug for oil-cups W ich shall keep the cup closed and which is capable of movement in the @up to force the o il', grease', or'other, lubricant out ofthe cup in quantitiesv according to such `1novement, while retaining part of the lubricant; A still further Object of the invention is to provide a grease-cupwith a hollow feed-plun`. ger to control the'discharge lof grease fromv the cup and a controlling device-for, .the plun The obj ect, st'll further, ofthe invention is to provide in a grease-cup a feed-y lunger to carry a portion ofthe grease and spring attachment carriedby the cup-stem and adaptedto enter the cup and engage the plunger for holding thelatter in various acljusted positions.

With these and various other objects and` advantages in view the invention consistsin a hollow feed-pluri er for grease-cups having an exterior racka' apted to bel engaged by a.

v holder carried bythe stem of `the cup and operated through the latter to permit various adjustments of the plungpr in forcingl discharges of lubricant from t e cup.

In the accompanying drawings, forming pif; oi' this application, Flgure '1 1s an elevation. Fig` 2 1s Aa vertical section showlng the Oiler charged. Fig. 3 isa perspectlve view of the spring-holder. Fig. 4 is a perspective f view of a modiiied formof springfholder."

The invention having special reference to oil-cupsfcarried bymovmg parts of, machiner and particularly locomotive-rods, a cu a apted to be fixed to'the -boxesof journa -bearlngs is here employed to exempllfy lSpecification of Letters Patent.

.. 'the invention; but its application is general,

' cup, an to hold the feedfplunger against accidental movement.- v

The shell 1-has acylindrical boreand a screw-stem 2, having a' discharge-orifice 3 extendin therethrough from the inside bottom of t e shell.

The exterior of the shellv maybe of any desired shape or conguration solong as it possesses a cylindrical bore andy 'an aperture 4, the purpose of which will be hereinafter ex lained. The feed-'plunger 5 .has a suitable ead 6, lfrom which extends a lcentral bore the length oi the'plunger to form a barrel'or receptacle 7 for part of the lubricant 8, the other art being held by the shell. The outer su ace .of the plunger is providodthroughout its length with a series O'f circular parallel ribs 9 and spaces or grooves 1 0,intervening the ribs to forma circular rack which ts the shell-bore closely The plunger-holder or retaining device consists of-a spring 1 1, projecting from a plate 12 andvterminating 1n a prong 13, having a.bev-.

eled end and turned at r1 ht an les to the body ofthespringxf The p ate 12 as a hole .14 to permit its .being slid over the screwduring the telescopic movement of the plunglelr-uin the shell and forms a closure for the vs e Y stem, where it is held between the bottom of the shell andpiccc' of machinery or journalboX -by,'st zrewingsaid stem into place. prong -13 exten4 sthr'ough the shell-a erture 4, and its beveled end engages the p rack.

. Referring ."toflthe modii'ication shown in "Fig. 4, the upper end ofthe spring 15is extended from the'prong 16 to form ahandgrasp 17.

The 'i unger- In'operation a slight ytap or blow on the plunger-headwill slide the plunger over the rong4'from. one rack-groove to another and orcesuiiicient vlubricant from the shell for one .ordinary oiling.y To removegthelun.

ier, the prong-4 is withdrawn sufficient y to.

ave it disengage .the rack; but to yinsert the plunger it-ls4 simply pushedtinto the shell and the spring tension oi" the rong will .per-

mit it to pass over the beve ed face lof the prong- It will be seenthatthe y"pl'l'iiiger not 'I elaini as new, and desire to secure by Letheeted j ournel or bearing the grease held by the plunger will liquefy and pass out of the cup. l

Having thus described my invention7 what ters Patent, is@

l. Agrease-eup comprising e shell, a. hollow plunger fitting vwithin the shell, and provided with a rack, and a plate-spring carried by .the shell and having e prong projecting into the rack to control the movement of the plunger.

2. In e grease-cup the combination, with a shell. having e screw-stein through Which grease is led, of e plunger 'fitting Within the shell and having' e circular rack formed by n series of ribs and grooves` and a. spriiigprong operated through the shell to engage therei'lr.

3. in grease-cup the combination, with a shell having n stem through which grease is fed, of a plunger @losing the shell sind adepted to contain grease, e circuler ruck on the which grease is forced, of u plunger slidub e in the shell :rnd havin Y e heedV ro`ecti11g above the shell, a series oi perelle ri s encircling v .the plunger and intervened by grooves to forni 'e rack, und a spring having. e. plete lit- 'Ling the seieW-sten'i to fix it and e prong on the free end of the spring adapted to work through the shell in mesh with the ruek.
